A newly-engaged Irish woman who has admitted killing her fiance in Sydney stabbed him in the back of the head more than 18 months before his death, a judge has been told.

Former housemate Isobel Jennings testified that the couple were arguing before she saw Cathrina Cahill come up the stairs with her hand behind her back and then suddenly stab David Walsh in the head three or four times.

Ms Jennings was giving evidence on Thursday at the New South Wales Supreme Court sentencing hearing of Cahill, from Wexford.

Cahill, 27, pleaded guilty at a previous hearing to the manslaughter of Mr Walsh, 29, on the basis of substantial impairment.

She had originally been charged with murder but the charge was downgraded.

Cahill, who is known as Tina, admitted unlawfully killing Mr Walsh - who was also from Wexford - between February 17 and 18 last year in the suburb of Padstow.

She gave psychiatrists a history of being in a traumatic relationship with Mr Walsh, hallmarked by physical, emotional and verbal abuse over a period of time.

Under cross-examination from Cahill's barrister, James Trevallion, Ms Jennings denied lying about the incident in which she said Cahill had stabbed Mr Walsh in October 2015.

The court was told Cahill was charged with one count of reckless wounding of Mr Walsh in relation to him being injured after she threw a large candle at him in November 2015.

She was convicted of the offence in her absence and placed on a two-year bond in April 2016 at Waverley Local Court.

According to the agreed statement of facts, the couple argued on the night of February 17 2017 when they were drinking with others.

They parted, before Cahill, two female friends and Matthew Hyde, a man they had socialised with at one of the pubs, arrived back at the Padstow address where Mr Walsh was either asleep or partially asleep on a couch.

Soon after, Mr Walsh repeatedly attacked Mr Hyde wanting to know who he was and, during the ensuing chaos, Cahill screamed: "Stop it Davey, get off, get off ... he's with Grace."

She tried to get a grip of her fiance's arms when he swung his arm back and she fell to the ground, the facts said.

She moved towards him and punched him in the face with a closed fist, before Mr Walsh pushed her again and tried to punch her in the face.

Eventually, "the offender opened and closed the cutlery drawer quickly taking out a large, very sharp, bladed knife".

One witness said over and over again "put it back" but Cahill replied: "No, he needs to be taught a lesson. It's not fair. Look at poor Matthew."

The hearing is continuing before Justice Peter Johnson.

Murder charges against Irish woman downgraded

A Wexford woman has pleaded guilty to the manslaughter of her fiance in Sydney, after the charge was downgraded from murder.

Cathrina Cahill, 27, pleaded guilty in the NSW Supreme Court on Tuesday, on the basis of substantial impairment “by abnormality of the mind”, to the stabbing manslaughter of David ‘Daithi’ Walsh between February 17 and February 18 in 2017 at Padstow.

Her barrister James Trevallion referred to the need for the judge to be aware of the “extent of the provocation and controlling behaviour” by Mr Walsh, before her sentencing hearing was set down for November 1.

Cahill remains behind bars where she has spent the past 20 months. Members of her family were in the court to support her.

ABC Australia has reported that doctors’ reports tendered to the court indicate that she may have been suffering from post-traumatic stress disorder at the time of the incident. 

Cahill admitted to unlawfully killing David Walsh – who was also from Wexford – between 17 and 18 February 2017 in Padstow. 

David Walsh, who was a father of three young girls in Ireland, was stabbed to death at his home.

He was pronounced dead at the scene after emergency services were called to the house on Watson Road.

According to AAP, Cahill’s barrister James Trevallion said the abnormality of the mind was caused by Walsh’s conduct towards her, stating that the judge needed to be aware of the “extent of the provocation and controlling behaviour” by him. 

The crown prosecutor told the court, ABC Australia reports, that she would need time to allow Walsh’s brothers and three children, who are in Ireland, to provide victim impact statements to the court. 

Speaking outside the court, Trevallion said Cahill was “doing ok”.
